«The speculator's chief enemies are always boring from within. It is inseparable from human nature to hope and to fear… The successful trader has to fight these two deep-seated instincts. He has to reverse what you might call his natural impulses. Instead of hoping he must fear; instead of fearing he must hope. He must fear that his loss may develop into a much bigger loss, and hope that his profit may become a big profit.»

«The big men of the Street are as prone to be wishful thinkers as the politicians or the plain suckers. I myself can't work that way. In a speculator such an attitude is fatal. Perhaps a manufacturer of securities or a promoter of new enterprises can afford to indulge in hope-jags.»
